A ketone test checks for ketones in your blood or urine. Ketones are substances that are made when the body breaks down fat for energy. Normally, your body gets the energy it needs from carbohydrate in your diet. But stored fat is broken down and ketones are made if your diet does not contain enough carbohydrate to supply the body with sugar (glucose) for energy or if your body can't use blood sugar (glucose) properly. Ketones can be tested in a laboratory.
Note: Fallingwater. (not Falling Water) Fallingwater, the house designed by American architect Frank Lloyd Wright for Edgar Kaufmann in southwestern Pennsylvania, hangs over a waterfall using the architectural device known as the cantilever.
Louis Henri Sullivan and Frank Lloyd Wright were the two primary influences. While Sullivan did not design residential homes (he was considered the father of the modern skyscraper), his philosophy of form follows function influenced young Frank Lloyd Wright and the other Prairie Style architects. Wright apprenticed six years with Sullivan and his influence can be seen in Wright's early work. Frank Lloyd Wright is the most well-known Prairie Style architect. He and several others shared loft space in the Steinway Piano Company building in Chicago, Illinois, beginning in the 1890s.
